These systems are a great way to supplement your heating oil costs. Heat pumps offer an energy-efficient alternative to furnaces and air conditioners for all climates. Like your refrigerator, heat pumps use electricity to transfer heat from a cool space to a warm space, making the cool space cooler and the warm space warmer. During the heating season, heat pumps move heat from the cool outdoors into your warm house. During the cooling season, heat pumps move heat from your house into the outdoors. Because they transfer heat rather than generate heat, heat pumps can efficiently provide comfortable temperatures for your home. Along with Mitsubishi, Bosch also makes a great heat pump product. And as with Mitsubishi, our technicians have been certified by Bosch to be an Accredited Bosch Contractor (ABC), which brings added benefits to our customers when we install these systems.
